IMPROVEMENT IN G-RAIN-SEPARATORS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern:

Be it known that I, GEORGE E. BRINGMAN, of Gettysburg, in the county ofAdams, and State of Pennsylvania, have invented certain new and usefulImprovements in Grain-Separators; and I do hereby declare that thefollowing is a full, clear, and exact description thereof,referencebeing had to the accompanying drawings, and to the letters ofreference'inarked thereon, which form a part of this specification, andin which- Figures 1 and 2 represent side views of my grainseparator, and

Figure 3, a longitudinal central section of the same.

The nature of my invention consists in the construction of agrain-separator, in which is employed a revolving perforateiil inclinedcylinder, supported at its outer or lower end, by suitable framing, andsupplied at its inner or upper end, within the casing of the separa tor,with a cogged surface, gearing into a pinion on the shaft or axle of thedriving-wheel, around which passes a belt, connecting with a pulley onthe shaft of the fan- 'ning-whcel, and providing the opposite end of theaxle of the driving-wheel with acam, engaging with a bar suitablyattached to the shaking-apparatus, for operating the same, in connectionwith such other devices as will be hereinafter described.

To enable others to manufacture and employ myinvention, I will nowdescribe its construction and operation.

In the accompanying drawings A represents a frame, which consists of twoupright boards, suitably braced at their upper and lower ends.

B represents another frame, placed in an inclined position, and securedat its inner or upper end to inner sides of the frame A, at the frontpart.

This frame is supported at its outer or lower end by means of pivotedlegs a a, which can be easily folded up out of the way, when desired.

0 is a perforated inclinedrevolving cylinder, encircled at its outer andinner ends by rings or wooden bands c c, which are connected together bymeans of bars or rods 0 c.

The inner ring 0 of cylinder-G is formed on its front surface with aseries of cogs, 0 into which gears a pinion, d, on the axle D of thedriving-wheel E; the object of said arrangement being to communicate arotatory motion to the cylinder 0.

F is the shaking-apparatus or sifter, which is supplied with the screensff, and inclined perforated bottom 9, which is reduced at its lower end,so as to fit into the upper end of the cylinder 0.

The shaker F is held in place by a loop, h, at its upper end, which isattached to one of the cross-braces at the top of frame A, and atitssides by cords or straps h h the cord 7:. connecting with a horizontalpivoted bar, i, at one end, and cord h with the upper end of a spring,m, made of whalebone, or other suitable material; the object of theabove being intended to allow the shaker to have an oscillating motion.

G designates the fanning-wheel, made as seen in fig. 3, and having thebearings of its axle in braces secured to the sides of the casing orframe A, over circular openings c in said frame.

' On one end 'of the axle j is a pulley, It, over which passes a belt,I, connecting with the driving-wheel E, for operating the fan.

at is a shield or protector, made semicircular in shape, and secured tothe inner sidesof casing A and crossbar 0, for the purpose of forming 'acovering for the fan G.

I is the hopper,into which the grain to be winnowed is placed, it beingprovided at its lower extremity, on one side, with an opening over whichslides a cut-011,1).

The lower opposite portion of the hopper is also provided with a numberof bevelled projections, 1X1), which are designed to separate the grainas it falls on the screens ff of shaker F, thereby preventing it fromdescending in masses, which will greatly facilitate the sifting-process.

The axle D is provided on the end opposite the drivin g-wheel E, outsideof frame A, with acam, s, so formed, that when the axle or driving-wheelis in operation, it will, in connection with pivoted ba'r i, againstwhich it strikes, and spring in on the opposite side of frame A, givemotion to the shaker F.

What I'claim, and desire to secure by Letters Patent, is-

l. The inclined perforated revolving cylinder 0, in combination with theframe B and cogs (l and c, all arranged, constructed, and operatedsubstantially as described.

2. The hopper 1, fan G, screens ff, inclined board F, cogs d and c, andcylinder 0, all arranged and operatcd substantially as set forth.

In testimony that I claim the foregoing as my own, I afiix my signature,in presence of two witnesses.

GEO. E. BRINGMAN.
